3 Claims.

This invention relates to pallets for sintering machines, the general object of the invention being to provide a steel frame connected with the end members of the pallet so that the device will have great strength and be comparatively light in weight and will not break or warp and if the end members should break, the frame can be attached to new end members.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a plan view of the improved pallet.

Figure 2 is a side view thereof.

Figure 3 is a section on line 3--3 of Figure 1.

Figure 4 is an end view thereof.

Figure 5 is a section on line 55 of Figure 1.

Figure 6 is a section on line 66 of Figure 5. Figure '7 is a plan view of the frame.

Figure 8 is a section on line 8--8 of Figure 7.

Figure 9 is a section on line 99 of Figure 7.

As shown in these views, I provide a steel frame A formed of the end bars 1, the side bars 2 and the intermediate bars 3. The bars 2 and 3 have rounded ends which are received in holes in the end bars 1 and the parts are welded together, as shown at4. The ends of the frame are bolted to the end members B and the ends of the bars 3 are extended and are received in holes in the end members and are upset into countersinks, as shown at 5. The ends of the bars 2 are attached to the end bars 1 in the same manner, as shown at 6.

The bars 3 are connected together at their centers by a vertically arranged web 7 and each bar 3 is connected to a bar 2 by a horizontal web 8.

The end members B, the end bars-1 and the web 7 are formed with aligning openings 9 for the reception of a shaft on which the track rollers for the pallet are carried. Also, to permit the pallet being shifted along the track, the end members B are provided with the spaced laterally projecting bosses 10 for engagement with the teeth of the drive sprockets of the sintering machine.

Bolts 11 are employed as a means to secure the end bars 1 to the end members B in addition to the. rounded ends of the bars 3.

Thus it will be seen that I have provided a pallet of great strength and light weight and the frame of which will not warp or break and if the end members should break, the frame can be used again on new end members.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the ap pended claims.

What I claim is:

1. A pallet comprising a pair of end members,

a frame comprising a pair of 'end bars and side and intermediate bars, the ends of the side and intermediate bars passing into holes in the end bars and the ends of the intermediate bars being extended and passing into holes in the end members, the ends of the bars being upset into countersunk parts of the holes and means for attaching the end bars to the end members.

2. A device of the class described comprising a pair of end members and a steel frame 'connected with said members, said frame comprising end bars, side and intermediate bars having their ends welded to the end bars, with parts of the intermediate bars fastened to the end members.

3. A device of the class described comprising a pair of end members and a steel frame connected with said members, said frame comprising end bars, side and intermediate bars having their ends welded to the end bars, with parts of the intermediate bars fastened to the end members and webs connecting the intermediate bars together and to the side bars.
